ALARMS AND WARNING MESSAGES
Your Lexus is equipped with alarms inside and outside, as
well as warning messages in the multi−information
display, that remind you if there is a problem involving the
entry function.
Cases which are expected to happen frequently are
shown in the illustrations and the other cases are
described in the table. If an alarm or warning message
comes on, check to see what the problem is referring to
the illustrations and table, and take the appropriate
measure.
If a warning message appears, the master warning light
will blink.
